Description

Photovoltaic louver
The invention relates to a photovoltaic louver installed on the building facade or openings, intended for protecting the building or the rooms inside it from the solar radiation and for generating electricity.
The solutions already known in the state of art include external photovoltaic louvers, installed on special, rigid frame structures made of metal profiles, rigidly installed on the building facade, or on the window or door frame. A solution where photovoltaic modules have the form of shutters is revealed in the invention description WO 2007/010575 A1 , whereas the patent description PL 218297 B1 discloses media louvers made of light fixtures placed in holders, formed by pairs of suspension cables.
The aim of the invention is to develop photovoltaic louvers with lightweight structure as well as high mechanical strength and resistance to changing weather conditions.
This aim was achieved by affixing the louver slats, containing photovoltaic modules, to suspension cables connected to brackets extending from the building facade. The photovoltaic louver, according to the invention, contains slats equipped with photovoltaic panels, suspended on holders formed by pairs of suspension cables, controlled by control lines, characterized in that the slat is an elongated, open profile, preferably of aluminum, its cross-section similar to an elongated letter C. The profile opening is closed by the photovoltaic panel inserted into the profile, protected with a strip combined detachably with one of the longer edges of the profile and the side walls enclosing the sides of the profile. In each of the side walls there is a pin used for suspending the louver slat on the suspension cable pairs, made preferably of stainless steel, and each pair of the suspension cables is equipped with ring holders, formed from a ring and cables encircling it, held together by means of ferrules pressed onto them, forming holders for the pins supporting the louver slats. On the side walls of each louver slat there is a second pin, at a distance from the point of support of the louver slat, placed in ring holders, formed from a ring and a pair of control lines encircling it, preferably made of stainless steel, held together by means of ferrules pressed onto them. The ring holder is a ring with a recess on the outer circumference, its shape corresponding with the shape of the side surface of the suspension cables encircling it. The ends of the control line are wound onto a tube, rotated by a winding/unwinding device, by means of which it is possible to control the inclination angle of the louver slats and obtain the optimum angle of the photovoltaic panel of the louvers relative to the direction of the Sun's rays. The length of the control line is so selected that the maximum angle of deflection of the slat bottom edge from the vertical plane passing through the axis of rotation of the louver siat is not greater than 180°.
The suspension cables are attached to brackets mounted on the building facade. The top attachment is comprised of eyebolts, with cut-outs in the ring forming the eye, into which the extreme ring holder of the suspension cable is inserted, combined with the eye of the bolt by means of a rod inserted into the bolt's eye and the ring holder of the suspension cable. The bottom attachment is a ferrule pressed onto the ends of the suspension cable, preferably made of stainless steel, with a thread on its end.
Preferably, louvers with a large surface area, for example louvers spanning a multi-story building, are equipped with intermediate attachment of suspension cables. The intermediate attachment is formed by an eyebolt with a cut-out in the ring forming the eye, with the ring holder of the suspension cable placed in it, pushed onto the pin mounted on the side wall of the louver slat. The threaded part of the eyebolt is seated in the ferrule seat, connected pivotably with the bracket on the building facade. The intermediate attachment provides rigidity for large-area louvers, and the pivoting connection with the bracket makes possible its rotation around the horizontal axis and is used to compensate linear distortions of the louvers, arising from temperature changes.
The suspension cables are preferably connected with the bottom brackets by means of springs compensating linear deformations due to temperature. The spring, connecting the suspension cable and the bracket, is attached to a rod inserted in the bottom extreme ring holder of the suspension cable, and the other end of the spring is attached to the eye of the bolt attaching the suspension cable to the bottom bracket.
Preferably, the axis of rotation of the louver slat is shifted relative to the center of gravity, so that the louver slat, falling under the force of gravity, always points the photovoltaic panel to the outside while the profile wall faces the building wall.
Preferably, the ring-shaped holders are round or elliptical and are made of stainless steel.
Preferably, the ferrules keeping together the lines, pressed onto the suspension cables and control lines, are made of stainless steel.
The advantage of the photovoltaic louver according to the invention is its light weight and easy access to a single photovoltaic module during the maintenance work, enabling quick replacement of a damaged part.
